I used JB Weld to bed my .25-06. She shoots top-notch now!

A couple of things I've found:

- Working hardness is acheived in about 8 hours
- Kiwi neutral shoe polish works great as a release agent
- Full cure after 24 hours means a good, hard steel-reinforced epoxy bed
- Much less viscous than Devcon and easier to use. I use both, and either one works great
- Did the bedding job about 1.5 years ago, and the epoxy is holding up fantastic

Can't wait to see the finished product!
